Five high-capacity AA batteries

The German company Varta traces its history back to the end of the 19th century. Today, the backbone of the brand's products are car batteries and batteries, both disposable batteries and rechargeable batteries. The Rechargeable Accu 2100 mAh model belongs to the category of the latter.

On a cardboard blister with batteries in the amount of 2 or 4 pcs. (depending on the selected configuration) the inscription “Ready to use” proudly flaunts, which encodes the absence of the need for batteries in the preliminary replenishment of energy reserves. You can put them into operation without leaving the cash register, since the low level of self-discharge contributes to long-term energy conservation. For a year of storage, model specimens lose on average less than 25% of the charge.

The actual capacity of batteries is almost always higher than indicated in the passport data — it varies in the range from 2150 to 2300 mAh, as someone is lucky. With such data, the Varta Rechargeable Accu 2100 mAh remote control will live almost forever, and the batteries will need to be removed from the camera ’s battery compartment for recharging many times less than when using conventional batteries.

The key to long battery life is a good quality charger. It is advisable to immediately discard Chinese “nonames” to the side, no matter how attractive their price tag looks, and preference should be given to solutions from trusted brands (“native” Varta chargers, as well as models from Panasonic). Another weighty argument in favor of Varta Rechargeable Accu 2100 mAh is that the cost is lower than that of its closest competitors. Let the savings turn out to be insignificant, but still pleasant.

" Duracell batteries last up to 10 times longer" — this slogan is familiar firsthand to the lion's share of ordinary people, as well as the brand symbol in the face of a pink hare. For professional use, the battery manufacturer has special offers in its range, in particular, high-capacity Duracell Turbo 2500 mAh batteries.

Rechargeable “finger-type” batteries have a survivability of about 400 recharge cycles and provide energy for “gluttonous” equipment — flashlights, lighting equipment, gamepads for game consoles, wireless mice, etc. The actual capacity of the batteries fully corresponds to the claimed values and reaches 2500 mAh.

"Out of the box" batteries are delivered ready for use, i.e. fully charged. They can lie idle in this form for more than a year — the Duralock charge conservation technology allows you to save the energy reserves accumulated in the tanks and ensures a low level of self-discharge. In general, batteries remain usable for more than 5 years.

On the shelves of Duracell Turbo 2500 mAh stores are presented in packs of 2 pcs. and 4 pcs.(less often). Also, the Turbo series has "relatives", sharpened to work in tandem with less volatile devices — a line of Duracell Basic batteries with a capacity of 1300 mAh. One or more of these batteries will be able to power gadgets with an average power consumption.

On a parallel conveyor with Eneloop batteries from the Japanese brand Panasonic, rechargeable batteries of the High Capacity series are produced — with increased capacity on board to meet the whims of energy-demanding equipment.

According to the "passport", the nominal capacity of the model is 2700 mAh. Plus or minus it is — deviations from the claimed indicator, if they happen, are usually within 50 mAh. However the label in small print prudently indicates the minimum allowable capacity of 2500 mAh, and in some batches of the product it is not far from this figure.

The self-discharge of batteries is higher than that of many peers, so they will most likely need to be charged in anticipation of use. But the loss of capacity in the cold of the Panasonic High Capacity 2700 mAh is minimal — at sub-zero temperatures of the order of -20 °C, it will be less than 15%. This means that when working in the cold, the batteries do not let us down.

The resource of the model corresponds to 500 charge-discharge cycles, which is the average value "in the ward." Those. even with intensive use, a set of rechargeable batteries will last for more than one year in a row. The mission of the batteries is to ensure the maximum duration of the devices on a single charge, and its Panasonic High Capacity 2700 mAh masters in full.

A twin of the famous "eneloops" (meaning Panasonic Eneloop batteries, which are trendsetters in the field of rechargeable batteries) are produced at the same production facilities as the popular relative. In fact, the differences between them come down only to different labels, and in terms of the elemental base, the batteries are like two drops of water.

The number "2450" in the full name of the model indicates the minimum guaranteed capacity of the battery tanks. In fact, its value is slightly higher and ranges from 2500-2550 mAh. At least 85% of the charge is retained after a year of storage in an unused form, which indicates their low self-discharge.

A lot of battery tests “walk” on the network, during which he was subjected to various tests and coped with them with a solid “five”. For example, the words of the manufacturer about maintaining the performance of batteries in cold weather have been confirmed in fact — at temperatures of the order of -15 °C, they continue to successfully cope with the duties shouldered on their shoulders to provide power to compatible devices ( cameras, external flashes and other equipment).

Positioned 1.2 In Fujitsu 2450 mAh gives out even with a weak charge. By the way, it is possible to charge the battery at any stage of discharge, which is facilitated by the absence of a memory effect. From the start, this will not be necessary, since the batteries are supplied already charged at the factory. Laudatory odes to the batteries of this series are also sung in numerous reviews, once again confirming the outstanding qualities of the model.

Each of the Eneloop series of rechargeable batteries is initially "refueled" using solar panels in accordance with the "green" certification system. Panasonic Eneloop Pro 2500 mAh is also no exception to this rule.

The pro version of the popular "eneloops" is a role model for all "finger-type" batteries. The model captivates with a large capacity (over the claimed 2500 mAh), stable operating voltage regardless of the level of charge remaining and high resistance to self-discharge. Thanks to the LSD (Low Self-Discharge) technology put into service, only about 15% of the battery charge is lost per year.

The scope of the Panasonic Eneloop Pro 2500 mAh is limited only by your imagination. And to the greatest extent, batteries appeal to amateur photographers and true photography pros — the model is one of the best options for autonomous power of flashes, other external light sources and other studio equipment.

The battery life is 500 recharge cycles. At least the manufacturer is talking about such figures and there are no good reasons not to trust him. As a result, Eneloop Pro rechargeable batteries can be recommended to absolutely everyone who is looking for a reliable and durable battery that can satisfy the energy hunger of the most serious consumers.
